To get a lot more power of the E92 M3 in NA form beyond bolt ons increasing the displacement is really the way to go. An extra 600cc's is a nice chunk to pick up made possible by the relatively short stroke in stock form providing quite a bit of room to grow. However, the LS6 V8 under the hood of the C5 Z06 is sill larger at 5.7 liters. With an aggressive cam only the Z06 can put out in the 420 wheel range and with exhaust and intake 450 wheel is within reason.

The S65 V8 at 4.6 liters is capable of 441 wheel horsepower. So, on paper, this actually makes for a fairly good race especially with a DCT M3. Yes, the C5 Z06 has a weight advantage but the M3's higher redline makes for a gearing advantage. So what is the problem? The 20 inch Hartge wheels the owner chose to put on his car which are basically boat anchors sapping power. The Hartge badge on the trunk clearly not making it up for it.

Furthermore, the 441 wheel number for a stroker M3 came from an RDsport setup, not Dinan. Dinan uses a fairly mild tune and has yet to demonstrate as high of dyno numbers with their motor. To really take advantage of this setup the M3 owner needs to ditch the wheels, get a new tune, and also look into Schrick cams as the stroker moves the peak of the powerband to the left. Much more horsepower is there to be had by moving the torque curve to the right towards redline with a more aggressive profile similar to how this Z06 gains power with its cam setup.

Enjoy the race, but seems silly for the M3 owner to spend all that money on the motor only to limit it in other areas.

GM "Cam only" is the same language as FBO to BMW owners. That's not a slow vette, but this is not really a fast M3.

IIRC the stroker cars make 430-440whp how they come, and FBO M3's are doing 390-410 with a solid dyno tune. More development will get better NA numbers with the stroker cars, but i'd bet they are all still in the 117-120mph trap range..

A few things... The C5 Z06 are fast stock..I have driven one and can tell you they are no joke especially modded! They weight around 3100 lbs and make 405hp. They run high 11's at 118-119 stock. As we all know all LS types V8s respond well to mods. The intake, cam, and exhaust push that car to 500hp easy. They make 430whp all day long..... That M3 is not slow it makes roughly to the same power but here is the reason it gets beaten so badly.. Weight! E92 M3s weight 3700lbs, Not to mention those Hartge wheels are really heavy! So were are talking 600 lbs + difference with same power.. The results do not surprise me.. As for being Dinan being overpriced I agree. But built engines for a car of this caliber are not cheap, I love the continuation of the NA philosophy personally.. FI is the way to go for power and per dollar on M3s hands down... ... To each his own... Give me the M3 any day.Take care

Ugh, this misinformation on forums is damn ridiculous. Especially when it's so easy to just simply search. Everything is on google. The E92 M3 weighs 3552 lbs. Inside line shows the weight at 3700 lbs but have tested a few in the 3500 range. Realistically, the E92 weighs 120 lbs more than the E46 M3. Not that much weight considering the overall size difference. ,

Its the power under the curve and tq curve of the Vette thats killing him. The weight merely multiples it and I will give anyone that concession all day. Still the M is very nice as a overall package. But as pointed out its so easy to mod that LS motor for power... Cam, springs and lifters, cold air intake and long tube headers coupled with a tune make silly power on the motor. Swap to a FAST intake and ported stock heads and near 500whp is obtainable with a driveable cam.

Even with the lighter weight you mentioned factored in I think the Vette just has superior power to weight and great gearing on its side. Its tq band doesnt hurt either LOL

If your goal is roll racing. I don't really see why someone would choose an M3. There is proven evidence other platforms are better and cheaper to build.

The M3 is complete package car. A car that can used as a daily driver, carry 4-5 passengers, and the owner can take it to road course on the weekends. In that sense, it is a fantastic car.

I really fail to understand this obsession of making the M3 a freeway racer or drag car. It is not developed from factory for any of that in mind.

you fail to see what i said. i said, its motor is lacking power. BMW delivered an awesome car, with a $#@!ty motor. comparitivly. does it do everything well? sure, but it would be a feared car if it came with more N/A power. how can you argue that? boosted S65's are crazy.. $#@!ty deal that you have to go aftermarket to get mid 400's and be competitive.. THATS what i said, regardless of which way way a foy retards tryi to twist it.

how is a 2 door, sporty, V8 powered, rwd car, not "the car" for a guy looking for a sporty 2 door, v8 powered, rwd car?

ill tell you why, because the motor isnt as stroing as the rest of the 2 door, v8 powered, rwd cars you can buy.. some for less, some for equal, and some for more..
